clear, concise, and exact description, referer'iee'ilie-ing" oftheaccompanying drawiii foiiiiin'gttfpart oftliis specification.

y tini'fention relates to cotton picking inacnine, "and has`for itsobject an in'iprovement in the construction of the picker columnsthereof, whereby the picking spindles may becaused to maintain definiteaxes of rotation with respect to the picker columns,

so that deinite relations will always be maintained between the pickingspindlesa'iid the internal mechanism of the cotton picking machines, andnotably the stri ping mechanism with which the picking spindlescoperate.

By ineans of my invention I have over.

come a diiiiculty iii the operation of cotton picking iiichines whichhas presented itself to ine in the field, for in the course oi. time,the bearings carried -by the picker columns have bccoii'ie worn to suchan'extcnt as to permit the spindles to wabble at their bear-4 ings,-thereby pcrii'iitting the points of the spindles to become deflected too.tar from the proper axesof rotation and planes of moveiiieiit of thespindles; the points of the spindles having frequently come intoin'ipropei" engagement willi the strippers, -occasioiiiiig destructionor impairment. of working parts Sept. 5, 05.

My invention will Vfully appear by reference to the aceonilianyinglrawi-i'ig and will lie-pointed out in the appended claim.
